The Moon's Birth May Have Given Earth Ingredients for Life | SciShow News

As astronomers find more and more planets around other stars, the big question we want to know is: are they habitable, could there be life there?
The vast majority of stars in the Milky Way are red dwarf stars, and most of the planets in habitable zones have been found orbiting these cooler, less massive stars. What are the chances that life could get going on these worlds?

Does Interstellar Panspermia Seed Life? Featuring Dr. Karen Meech

John Michael Godier discusses if there could be life on ice shell moons like Europa and Enceladus and the possibility of interstellar objects such as Oumuamua seeding life on other planets with Dr. Karen Meech of the University of Hawaii which discovered the first interstellar object Oumuamua, with the Pan-STARRS 1 telescope.

Is Life Universal? Featuring Dr. Avi Loeb

John Michael Godier and Dr. Avi Loeb of Harvard University and Harvard Smithsonian Center for Astrophysics discuss whether it's possible for life to survive and thrive in the Trappist-1 solar system.
TRAPPIST-1, designated as 2MASS J23062928-0502285, is an ultra-cool red dwarf star that is slightly larger, but much more massive, than the planet Jupiter; it is located 39.6 light-years from the Sun.

Life on Mars? Rock varnish might have an answer

If life exists on Mars, it still hasn’t showed itself, but recent evidence from the red planet increasingly supports the possibility. Life could have developed there. Most of the conditions are right and nothing found so far rules out the possibility, either in the distant past or today.
If something is or was alive there, it’s probably tiny. Since microbes make up the vast majority of life on Earth, microbes are the most likely thing to find somewhere else. It’s not so easy figuring out what “alive” means on another planet—let alone finding a living microbe.
The upcoming Mars 2020 mission and its rover-based mobile laboratory will take another giant step toward answering the question. First, though, science needs to answer some questions about life here on Earth. It turns out that the dark, hard manganese oxide in varnish coating cliff faces and rocks throughout the American Southwest and elsewhere has a lot to say about the subject.

About The Planetary Society:
The Planetary Society has inspired millions of people to explore other worlds and seek other life. With the mission to empower the world's citizens to advance space science and exploration, its international membership makes the non-governmental Planetary Society the largest space interest group in the world. Carl Sagan, Bruce Murray and Louis Friedman founded the Planetary Society in 1980. Bill Nye, a longtime member of the Planetary Society's Board, serves as CEO."

It’s well-established that the Martian surface is completely inhospitable to life as we know it, but recent research suggests that may not be the case down below.

Discovering a Lake on Mars, and could it hold LIFE?! The Case for Mars 32

In this episode of the Case for Mars, we look at the recently discovered lake on Mars, and how it was discovered. We discuss the MARSIS experiment, that is able to use Ground Penetrating Radar to detect changes in minerals, ice, or liquids underground. We also discuss what NASA thinks about this discovery, and whether or not life could exist in this lake.

Researchers Suggest Life Could Have Existed On The Moon

The Moon doesn’t appear to have what it takes to support life now, but researchers suggest that wasn’t always the case.

Researchers Suggest Saturn's Largest Moon Titan Has Potential To Produce Life

According to a report by Geek.com, a new study suggests that Saturn’s largest moon, Titan, may have the potential to produce life as we know it. A team of researchers using data from the Cassini spacecraft examined the icy moon looking for biological molecules. Leader of the study Catherine Neish, found that when exposed to liquid water, organic molecules like the ones on Titan are capable of producing a range of biomolecules, including amino acids. Neish and her team reportedly focused their attention on craters, particularly Sinlap, Selk, and Menrva. The team wrote, “We determine that the best sites to identify biological molecules are deposits of impact melt on the floors of large, fresh impact craters."

*New forms of Quark Matter
There’s growing speculation in physics about the possibility of new forms of matter existing beyond the periodic table – creating a sort of continent of stability composed of exotic quark matter.
*The end of the Australian Astronomical Observatory
The Australian National University has taken a lead in the new consortium of 13 universities which have taken over the operations of the Australian Astronomical Observatory.

Since it is organized and attended by only graduate students, post docs, and select undergraduates, AbGradCon is an ideal venue for the next generation of career astrobiologists to form bonds, share ideas, and discuss the issues that will shape the future of the field.

The power of Dark Energy may be increasing as the universe ages. Subtle clues are emerging that the accepted model for the nature of dark energy and dark matter may not be all that. We saw the first such clue recently in our recent episode on the Crisis in Cosmology. Today we’re doing a Space Time Journal Club to reveal another clue. We’re looking at a new paper in Nature Astronomy, “Cosmological constraints from the Hubble diagram of quasars at high redshifts” by Risaliti and Lusso. It hints that the cosmological constant may not be so constant after all. In fact it may be increasing. If this is true, then our prediction for the future of our universe looks VERY different, and may involve the entire universe tearing itself to shreds at the subatomic level in the Big Rip.
On this edition of Space Time Journal Club we look at:
Risaliti & Lusso (2019) "Cosmological Constraints from the Hubble Diagram of Quasars at High Redshifts"

NASA ScienceCasts: A Super Start to 2019

2019 is an excellent year to look to the sky and enjoy the spectacular view of Earth’s nearest neighbor, the Moon.
NASA Science: http://science.nasa.gov/

Do black holes contain dark matter?

Black holes grow by accreting matter under gravity; so surely they should be able to accrete dark matter? So then is there loads of dark matter trapped inside black holes?
Turns out it's a bit more complicated than that because of what we know of how dark matter behaves - which isn't a lot! - but it's enough.
This was a really fun speculative question to think about, especially because it ties in with my PhD thesis too. Let me know if you want me to do a video describing my thesis down in the comments.
Both my lapel microphones ran out of battery this week. Thankfully one of them didn't need a battery to use with a smartphone, so the sound was recorded that way. It's not brilliant I know, but it'll do. My research schedule this week stopped me from delaying filming until I could get a battery. The sound suffered so science wouldn't.
iIf you have questions you want me to answer either tweet them to me (https://twitter.com/drbecky_) or leave them in the comments below. I'm more likely to see stuff on Twitter!

Space Weather News | A Filament Sandwiched by Sunspots 03.20.2019

UPDATE: Part of the filament I talk about did erupt after I posted this video! We could have a part-Earth directed solar storm coming by the end of this week! Check my twitter feed for the latest on arrival time!
Original Video Description:
This week we are coming down from a solar storm from some fast solar wind, but that doesn't mean the fun is over! We have two fast-growing sunspots on the Earth-facing Sun and they are sandwiching a filament that is growing more unstable by the day. If this filament erupts within the next day or so, we could have an Earth-directed solar storm! We are keeping a close watch on this to be sure. Also, one of the new sunspots may be showing signs of an influence of solar cycle 25. Just like the previous rogue sunspot we saw a few weeks ago, this new region has a dominant magnetic signature that runs north-south instead of east-west. Its too early to tell what the final polarity of this region will be, but if it continues this way, it will be yet another signal that solar cycle 25 is closer than we think! Learn the details of this filament sandwich, get the scoop on the two new sunspots that may cause its launch, and see what else our Sun has in store for us this week!
